Abstract: ABSTRACT: "Methof of access control in a communication system."           In a communication system having a plurality of mutually independent subscriber stations these stations seize a common duplex transmission channel for establish-ing a connection in accordance with a multiple-access method. To prevent simultaneous access and the resultant access destruction and also in the case of frequent access destruction of the blocking of the common duplex transmission channel, each transmission station, to initiate a transmission therefrom, seizes the duplex transmission channel by means of a signalling character. The signalling character is transmitted by the subscriber station during a time slot allocated for that purpose.          To distinguish between reporting subscriber stations a pulse function from a system of orthogonal or substantially orthogonal pulse functions is used as an identification character. The subscriber stations occupy the duplex transmission channel in time slots authorized for access, uncoordinated in time, with, for example, a randomly selected orthogonal pulse function.

Abstract: Abstract A TIME-SPACE-TIME SWITCHING NETWORK USING A CLOSED-LOOP LINK            A switching network for selectively connecting at least one input time-division channel on an input link  (IL)  to at least one output time-division channel on an output link (OL). The network is organized around a closed-loop link on  which  circulates  a  multiplex  message  carrying  512 time-division exchange channels. The input and output links are respectively multiplexed onto an input multiplex link (IML) and an output multiplex link (OML) which are coupled to  the  closed  loop  by  a  switching  module  (SM).  Each switching module comprises an input buffer (IB), an output buffer (OB) and a local buffer (LB) the addressing of which is selectively controlled by a time slot counter (CTR) or a corresponding   pointer   memory.   So-called   "broadcast" connections coupling one input channel to several output channels, and "in-cast" connections coupling several input channels to one output channel, can be established. Each of these connections uses only one exchange channel.

Abstract: Abstract:           The invention provides a process for manufacturing a semiconductor device and the semiconductor device so produced.  In particular, the process permits a semiconductor pellet to be sealed in an epoxy resin in a manner that does not require the use of a mold.  The epoxy resin is dropped onto the pellet as the pellet is turned.  The epoxy resin its then heated at 160-180°C for 2 to 10 minutes as the pellet is turned, so that the surface portions  of the epoxy resin are hardened. The resin is then heated at 160-200°C for 3 to 24 hours while the pellet is kept stationary in order to complete the hardening of the resin.  The avoidance of the use of a mold means that a very satisfactory device can be mass produced quickly and efficiently.

Abstract: ABSTRACT       In this pipe connection, the pipe end part is pressed, as a result of cold-forming in zones, by means of a press ring     to be displaced axially, to form a positive leak-proof connection with a connection piece     inserted into the pipe end part and belonging to a pipe fitting    .  A sleeve     to be pushed onto the pipe end part is provided with an annular outer bead and, then the press ring is pressed on, is deformed in such a way that the sleeve material is displaced radially inwards in the bead zone , the pipe end part and connection piece acquiring an annular recess   .   Moreover, the press ring   has at its rear end an annular inner bead      which at the same time displaces the sleeve material radially inwards at the rear sleeve end, as a result of which further pressing takes place at the end      of the connection piece    .  The gap between the pipe and connection piece is thus closed, so that no crevice corrosion can occur.         (Figure 1)

Abstract: ABSTRACT OF THE INVENTION         A pivotable steering column is adjustable to any of a number of angular positions defined by the teeth of two elements of a first locking device   A manual lever can be raised to disable the first lock and allow selection of a different steering wheel inclination.  The steering wheel can be moved to its uppermost position by lowering the manual lever once.  In this case, the first lock  maintains  engagement  of   the   teeth  of   the aforementioned two element, and a powerful spring pulls the steering  column  upward  to the uppermost position irrespective  of  the  first  lock.  A second lock then becomes wedged between the pivotable and stationary parts of the steering column, thus holding the former in the uppermost position.  Lowering the manual lever a second time disengages the second lock, allowing the steering column tilt cown from the uppermost position.  Thus, the steering column returns  to an originally set driving position defined by locking engagement of the first lock.
